摘要

The average bit-error rate performance is studied for a coherent free-space optical communication system employing differentially encoded quadrature phase shift keying with the Mth-power phase estimation method. A closed-form expression, considering the combined effects of the M turbulence fading, pointing errors and phase estimation errors, is derived in terms of the Meijer''s G function. Numerical and Monte Carlo simulation results are presented to verify the derived expression.
